Abstract: A tiny pre-amplifier for a small, low voltage, high impedance signal source, usually an electret microphone, exhibiting near unity gain, has an input cascode stage connected to the microphone and a matched balancing cascode stage; both cascode stages are energized from the same power supply circuit. The two cascode stages supply intermediate signals to the inputs of a differential amplifier to generate an output signal having a greatly reduced noise content, independent of power supply variations. The pre-amplifier is wholly integratable, has low power drain, and fits into the microphone housing.

Abstract: An improved circuit board material having a support layer, an electrical resistance layer and a conductive layer. The circuit board material has a resistance of at least about 500 ohms/square. The circuit board material is formed by electro-plating the electrical resistance layer on the conductive layer. The conductive layer is desirably activated prior to electro-deposition of the electrical resistance layer thereon. The conductive layer is activated by contacting with an activating agent such as benzotriazole electrolytic chromate and the like. A preferred electro-plating bath for electro-deposition of the electrical resistance layer comprises about 0.5 mole per liters nickel hypophosphite. The disclosed electro-plating bath functions at ambient temperatures and is effectively temperature independent. Circuit boards can be formed from the circuit board material through a process involving only two etching steps.

Abstract: A color cathode-ray tube (CRT) has a rectangular faceplate panel with a major axis and a minor axis. A viewing screen is disposed on an internal surface of the panel. The panel is sealed to a funnel along an edge of a sidewall of the panel. A color selection electrode assembly is spaced from the screen and attached to the sidewall of the panel. An internal magnetic shield has a substantially rectangular base with four corners which is secured to the color selection electrode assembly, and a flange circumscribing an aperture. A substantially continuous shield sidewall extends between the base and the flange. The shield sidewall extends backward along an inner surface of the funnel. The internal magnetic shield is improved by at least two pairs of strengthening ribs which are formed in opposite sides of the shield. The ribs are substantially parallel to the minor axis of the panel and in proximity to the flange of the shield.

Abstract: A car security system has a proximity sensor such as a radar sensor with variable sensitivity and capable of producing a detection signal upon detecting motion of a person in a monitoring area. A control circuit is provided controls the sensitivity of said proximity sensor. The system also has a monitoring/alarming control circuit for control of predetermined monitoring and alarming control on the basis of the output from the proximity sensor, and alarming devices such as a headlight flash circuit, buzzer and siren for performing a predetermined alarming operation under the control of the monitoring/alarming control circuit. The sensitivity control circuit operates in response to a predetermined operation such as an arming start operation to vary the sensitivity of the proximity sensor so as to automatically set the sensitivity to a first sensitivity level which is the highest level within a range which does not cause the sensor to produce the detection output.

Abstract: A method of monitoring the sound within a car is disclosed. The occurrence of abnormality indicative of possible auto theft is reported to the driver who is remote from the car by means of the anti-theft system which transmits the occurrence of abnormality to a remote control unit and which turns on the power of the mobile telephone system, so as to make it ready for receiving external calls. The anti-theft system transmits to the driver the sound within the car collected by the microphone of the mobile telephone system, thereby making it possible for the driver at a remote place to ascertain the state of the car.

Abstract: Under one embodiment, a first and a second similarly constituted detector, and an OR gate coupled to the two detectors, are provided to a digital video system. The first detector detects quantization errors of numerically adjacent values in vertically adjacent pixels of a current frame. The second detector detects quantization errors of numerically adjacent values in horizontally adjacent pixels in the current frame. The OR gate is used to determine whether quantization errors of numerically adjacent values are detected in at least one of the two spatial dimensions of pixel adjacency in the current frame. In one variation of this embodiment, a potential quantization error lookup table that supports concurrent lookups for vertically and numerically adjacent quantization error detection as well as horizontally and numerically adjacent quantization error detection is used and shared between the two detectors.

Abstract: A tiny electret assembly for an electroacoustic hearing aid transducer, either a microphone or a sound reproducer, includes a thin, flexible, planar diaphragm and a planar backplate, the diaphragm and the backplate constituting the electret electrodes. One of the two electrodes is permanently charged to a given differential voltage relative to the other and the two electrodes are mounted, in the transducer, in fixed, spaced, substantially parallel relation to each other; the differential voltage between the electrodes pulls a central portion of the diaphragm toward the backplate, tensioning and stiffening the diaphragm. The mount for the diaphragm permits movement of the diaphragm rim in the plane of the diaphragm but precludes movement of the rim of the diaphragm perpendicular to the plane of the diaphragm (and the backplate) so that the diaphragm cannot buckle. Different rim mounts for the diaphragm are described.

Abstract: An automatic kinescope bias (AKB) arrangement embodied in an integrated circuit (IC) includes circuitry for generating a timing signal during an AKB test interval, circuitry for generating a test signal in response to the timing signal, and circuitry including an output terminal for coupling the test signal to the kinescope. The AKB IC also includes an input terminal and a switching element coupled between the input terminal and the output terminal and responsive to the timing signal for selectively decoupling the input terminal from the output terminal. In a television system which includes a bias network which is coupled to the output of the video signal source and which inhibits the kinescope from being cutoff during the AKB test interval, the input terminal of the AKB IC is coupled to the output terminal of the video signal source. This allows the bias network to be decoupled from the display device during the AKB test interval, thereby preventing the bias network from affecting AKB operation.

Abstract: An autoequalizing hybrid circuit for providing a cancelation path to minimize the two-wire receive path signals that are reflected onto a two-wire transmit path from a subscriber line interface circuit is disclosed. The hybrid circuit includes a variable impedance balance network. A tone generator injects a set of equalization signals into the receive path which are used to control the setting, or equalization, of the balance network. The tone generator also generates a supervisory signal into the receive path used to monitor the performance of the balance network. A detect circuit monitors the level of the reflected equalization sidetone signals and produces balance signals whenever the equalization signals fall to a null level. The detect circuit also monitors the supervisory sidetone signals and produces a recalibration signal whenever an abrupt change in the signals indicates that the balance network is no longer adequately cancelling their reflected signals.

Abstract: An architecture is provided for testing and emulating an integrated circuit with embedded function blocks. The output nodes of the function blocks are connected through a tri-state buffer to a test bus which in turn is connected to configurable external pins. The external pins multiplex the normal I/O in normal mode and the test bus I/O in the test mode. The test bus is also connected through multiplexers to input nodes of function blocks. In test mode, the function block nodes are accessed through the test bus. For emulation of an embedded microcontroller or microprocessor, the internal connections of the microcontroller (or microprocessor) are brought out to those external pins which in normal operation are connected only to the microcontroller and not to any other function block. An in-circuit emulator (ICE) emulating the microcontroller is connected to the other function blocks through those external pins.
